H-bridge driver IC for low-voltage (2.5V) operation

The IC adopts a four-port interface control technique using the PHASE and ENABLE signals. Control is secured using just three ports, unlike previous devices that required all four ports for full step control of a stepper motor. This addresses challenges in applications where the lack of MCU control ports is an issue.


The TC78H620FNG is compatible with low-voltage drives (for motor drive: 2.5V and above, for logic control: 2.7V and above) making it suitable for mobile devices with a 3.7V lithium-ion battery drive. Either two DC brushed motors or a single stepping motor can be controlled. A maximum current consumption of 1 µA in standby mode contributes to reduced power consumption. In an SSOP16 package, it incorporates motor protection and safety features including overcurrent detection, thermal shutdown and under-voltage lockout functionality. In addition, shoot-through current protection supports motor control without needing to consider deadtimes when switching output ON and OFF.
